Acceleration Converter (m/s², g, ft/s², Gal)

Convert acceleration between m/s², standard gravity (g), ft/s², and Gal (used in geophysics/seismology). Runs entirely in your browser.

How it works

Every unit is converted through a common base unit — meters per second squared. "g" here means standard gravity (9.80665 m/s²), the reference used to describe forces felt during acceleration (e.g. "3g in a fighter jet turn"), not the gram (a unit of mass).

FAQ

What does "3g" mean?

Three times the acceleration due to standard gravity — about 29.42 m/s². It's a common way to describe forces felt during rapid acceleration, braking, or turning.

What is a Gal?

A centimeter per second squared (0.01 m/s²) — a small unit used mainly in geophysics and seismology to measure ground acceleration during earthquakes.
